前端小纠结--VS Code调试配置分享

这不是一篇科普文,只是一篇浏览器调试配置的分享(主要对准对准vs code调试)

调试配置

使用vs code插件debugger-for-chromedebugger-for-edge(EdgeHTML&Chromium)Debugger for Firefox调试之前,会自动在工程下添加.vscode文件夹,里面的launch.json就是配置调试参数的位置。

launch.json

很多的配置参数,具体看参考章节的nodejs-debuggingdebugging-protocol

launch模式

launch模式就是重新打开一个浏览器实例(不是tab)。

attach模式

attach模式,是附加到现在已经打开的浏览器调试端口上,所以需要你在已经打开的浏览器中访问launch.json中配置的网站地址。

attach模式的tab窗口选择

chrome配置

  • windows

chrome配置远程调试端口

  • mac

    终端执行: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222

  • Linux

    终端执行: google-chrome --remote-debugging-port=9222

Edge(Chromium)

  • windows

Edge(Chromium)调试端口配置

命令行:msedge.exe --remote-debugging-port=2015

  • mac和Liunx现在官方没说怎么调试.....

Microsoft Edge (EdgeHTML)

  • windows

    命令行: microsoftedge.exe --devtools-server-port=2015

    竟然不能快捷方式配置,不科学。

个人建议

个人建议平时开发,把端口配置到快捷方式,使用attach模式可以共享使用已经安装的浏览器插件。

具体还有很多参数配置,可以参考官方文档。
